Help with JTextArea, resize windows

[paul]

How can I get the JTextArea to display without having to resize the window?
And is there a way I can position it?

Code:

import javax.swing.*;
import java.awt.*;
import java.util.Random;

public class Oval extends JPanel {
    
    public void paintComponent( Graphics g ) {
        super.paintComponent( g );
        
        Random randomNumbers = new Random();
        int width = 1 + randomNumbers.nextInt( 200 );
        int height = 1 + randomNumbers.nextInt( 200 );
        
        double area = Math.PI * (width/2) * (height/2);
        
        String text = "Area = " + area + "\n";
        JTextArea textArea1 = new JTextArea( text, 10, 10 );
        
        add (textArea1);
      
        //( int x, int y, int width, int height )
        g.drawOval( 10, 10, width, height );
    }
}

Code:

import javax.swing.JFrame;

public class OvalTest {
        
    public static void main(String args[]) {
        JFrame frame = new JFrame( "Oval of random size" );
        frame.setDefaultCloseOperation( JFrame.EXIT_ON_CLOSE );
        frame.setSize( 600, 210 );
        
        Oval oval = new Oval();
        
        frame.add(oval);
        
        frame.setVisible( true );
    }
}

Thanks

You need to learn layout managers to be able to place the component to the position you want.
